A proof-of-concept exploit has been made public for a recently patched vulnerability in OpenSSL that can be exploited for denial-of-service attacks.
OpenSSL versions 1.1.1d, 1.1.1e and 1.1.1f are affected by a high-severity vulnerability that has been described as a segmentation fault in the SSl check chain function.
Security researcher Imre Rad has published a PoC exploit for the vulnerability, along with a description of the exploitation process.
CVE-2020-1967 was the first vulnerability patched in OpenSSL in 2020.
As SecurityWeek reported a few months ago, OpenSSL security has evolved since the disclosure of the Heartbleed vulnerability back in 2014.
